The purpose of this study is to construct a finite-element (FE) model which can accurately simulate the behaviour of golf impacts, and to investigate the effect of a shaft on clubhead upon the rebound behaviour of a ball, by conducting an FE analysis of a ball colliding with a simplified club. The clubs were constructed by holding the simplified clubheads by the locking ring which is fitted onto a steel shaft. Three clubheads (circular hollow bodies) of constant mass, made of a titanium alloy, with increasing loft angle were manufactured based upon the mass, volume and position of centre of gravity (COG) of commercial clubheads. The FE models of the clubheads, which consisted of clubheads, locking ring and shaft, with linear elasticity, were constructed. The FE model of the ball consisted of 8-node solid elements, and the material model was expressed as a viscoelastic model with hyperelasticity. Impact experiments were also conducted to confirm the accuracy of the FE models, by comparing the results of the experiments to those of the FE analyses. The results of impact simulations closely matched the experimental results. The impact behaviour was analysed by varying the impact point of the ball colliding with the full clubs and the singular clubheads; the results for the collision between the ball/clubs and ball/clubheads were compared. The difference between the two extreme values for the rebound angle and the spin rate in the case of the club impacts tended to become smaller than that of the clubhead impacts. This tendency is estimated to depend on the relationship between the shaft position and the loft angle/COG of the clubhead.
